LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Nov. 2, 1909.

To all whom it may concern:

Be it known that I, EDGAR P. WEBSTER, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Loose-Leaf Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to My invention relates to loose leaf binders, but more particularly has reference to that class of such devices in which complementary hook elements are provided that are capable of being opened or closed.

The object of my improvement is to greatly facilitate the assembly and operation of the hook carrying elements, and furthermore to enable all the hooks to be opened or closed and locked in closed position by a single element.

Vith these ends in View my invention consists in the combination and arrangement of parts hereinafter fully set forth and then particularly pointed out in the claims which conclude this description.

In the accon'ipanyii1g drawing Figure l is a plan view of my improved loose leaf binderl*ig. 2 a plan view of the same with the top casing removedl*ig. 3 a cross section at the line 00, m, of Fig. lFig. l a

(3 an lnterior plan illustrating a seriesot'loosev leaf binders constructed in accordance with my improvement, and Fig. 7 is a detail inner edge View of one of the hook carrying arms.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 is the bottom casing which is provided with integral upstanding sides 2 that are turned inwardly so as to form lateral edges 3.

4 are the hook carrying arms which are grooved as seen at 5 lengthwise of their outer surfaces and in assembling these arms these grooves are merely engaged with the edges 3 whereupon they will readily slide so as to assume their proper place within the casing, and this manner of assembling these arms with respect to the casing will bring the complementary arched hooks 6, carried by said arms, above the plane of the edges 3 so that it is not necessary to form any notches within the bottom casing in order to allow for the movements of these hooks in opening and closing. These armsd are formed with inwardly extending lugs 7 the inner edges of which are provided with in-v tel-locking tongues 25 and notches 9, and grooves 10 are cut lengthwise of the inner edges of said lugs, and through these grooves extends a pintle lever 11 which constitutes the means for pivoting together the oppositely disposed lugs.

The object of the tongues and notches is to cause the lugs to be closely associated so that the pintle' lever will not become displaced during the operation of the hooks, and while I prefer this construction, I do not wish to be limited thereto since the inner edges of these lugs may be grooved and the tongues and notches omitted, as is shown in the Letters Patent above referred to.

The pintle lever 11 has oil'set portions 12 while one extremity of said lever is provided with any suitable crank or handle 13, and the casing is closed by the cap plate 14 which isprovided with small gates 15 to allow for the movements of the hooks in opening and closing. By turning the lever ll to the position shown at Figs. 1, and 3, the ol'l'sets l2 will extend in a vertical plane against the plate ll, 'and the hooks (i will therefore be locked in closed position so that they cannot be manually opened. By turning the lever 11 in tlre reverse direction these otlsets will be caused to bear against the bottom of the casing, as shown at .l ig. 4, and by the continued turning of this lever the olfsets will operate against the casing after the manner of a cam, and the lever and lugs will be elevated and the hooks thereby opened.

\Vhen the lever is turned so as to'cause the oti'sets to bear against the cap plate 14 the lugs will thereby be thrown downwardly and the hooks closed.

It will be apparent that the journalingof the side arms to the edges of the casing will enable the rocking movemcnts'of said arms to be effected with great facility, and, moreo\er,'this method of journaling brings these arms higher up in the casing so that the normal plane of the hooks is elevated, thereby (hing away 1 11.111" w lling E pinfle have? extending lengthwise of said 30 the (25 gs f the Cu 1031 of the mu) f Assad]? casm i hrough'flme grooves in the lugs and and pmvn WED 01 portions, and the cap sliding of spect to lhfi casim been nssemb Ween Una iu In the com 1 ction shown a single pair of colnplen'm 10 Shawn, 1 piovids tvnis ofi's mediate vicinity of the lugs 50- 111: the. alttel will 2103 as stops is prevent lengthwise displacement of the pintie 1.9,
